The speaker discussed creativity and how it is important for problem solving. They defined creativity as the key to tackling problems and finding smart solutions. While most children are naturally creative, only about 2% of adults retain their creativity. The speaker argued this is because creativity is not fostered in schools, which only reward one right answer, or in our social environments that discourage thinking differently. However, creativity and innovation are linked and important for success in all areas of life. The speaker provided examples of how fostering creativity through exposure to new challenges and unexpected experiences can increase innovation and flexibility.
